摘要分析了他励直流电动机的机械特性,然后分析并励直流电动机的机械特性,并与他励直流电动机的机械特性相比较,得出它的不同点：空载转速不随电压U_a变化,而机械特性曲线的斜率随U_a的增大而减小。这为更好地使用并励直流电动机提供理论依据。 The mechanical characterstics of the separately exited DC motor was discussed, the mechanical characteristics of the shunting exited DC motor, and theirs difference was drawn by comparing： the no-load speed is constant and independent of the voltage Ua, the slope of the torque speed curves decreases with increasing Ua. It offers the theoretical foundation for using the shunting exited DC motor better.
